Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomatoes
Provide the main body, flavour and acidity of the soup.
Butter
Adds richness and carries flavour from the sautéed vegetables.
Flour
Thickens the milk and soup so it has a smooth, body-rich texture.
Milk
Adds creaminess and mild sweetness, softening the tomato's sharpness.
Cream
Adds richness and a smooth, velvety mouthfeel to the finished soup.
Onions
Build a sweet, savoury base through gentle frying.

The step that matters

Adding the soup to the cream. Cream can curdle or separate when it gets too hot or meets acid suddenly. Adding the soup slowly to warm cream, without letting it boil, keeps the texture smooth.

Flavor stand-ins for the clove

How well each one fits the dish's main ingredients (tomato, sauce, carrot, butter, milk, onion, flour):

  1. Celerybetter flavor fit
  2. Parsleybetter flavor fit
  3. Capersbetter flavor fit
  4. Clovethe original

Fit is the average pairing score against tomato, sauce, carrot, butter, milk, onion, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
